No .. this is pure assumption.
We know what Jesus specifically taught. There are 4 gospels in the Bible [ for some reason ] .. we can specifically see what Jesus taught from these. That's all.
The gospel of Luke was written by some unknown author who relied on unspecified second hand accounts, who is assumed a pal of the false prophet Paul. Mark, some unknown author, who was assumed a pal of the "worthless shepherd", Peter, who is suspect on those grounds alone. John's gospel was more weighted as a commentary of John than a witness to the testimony of Yeshua. All these "gospels" were edited by the Roman church, including Matthew. If you want to know what Yeshua brought to light, you might want to first look to the Scriptures, the Law and the prophets (Matthew 5:17). That is his source material.
